inhibited by the new sulfonamides, with KIs in the range of 0.75-8.8 nM. hCA IX, a tumor-associated isoform involved in cancer progression and metastatic spread was potently inhibited by the new sulfonamides, with KIs in the range of 2.3-87.3 nM, whereas hCA XII, and antiglaucoma and anticancer drug target, was inhibited with KIs in the range of 6.1-71.8 nM. It is noteworthy that one of the new compounds
通过克莱森-施密特缩合反应,从各种查尔酮和4-氨磺酰基苯甲醛制备了一系列姜黄素激发的磺酰胺衍生物。所有新化合物均作为金属酶碳酸酐酶的四种人同工型(hCA,EC 4.2.1.1)同工型hCA I,II,IX和XII的抑制剂进行了分析。观察到针对所有这些亚型的有趣的抑制活性。hCA I,一种与几种眼部疾病有关的同种型,在KIs的范围内为191.8-904.2 nM,hCA II,一种抗青光眼药物的靶标,被新的磺酰胺类药物高度抑制,KIs在0.75-8.8 nM范围内。hCA IX是一种与肿瘤相关的同种型,与癌症的进展和转移扩散有关,被新的磺胺类药物有效抑制,KI的范围在2.3-87.3 nM之间,而hCA XII,抗青光眼和抗癌药物的靶标为 KIs在6.1-71.8 nM范围内被抑制。值得注意的是,发现新化合物之一5d对hCA II(KI = 0.89 nM)的选择性是hCA IX和hCA XII的近9倍,而5e对hCA
